The invention relates to new and useful improvements in easy opening containers, and more particularly to a container which may be hermetically sealed.v

An object of the invention is to provide an easy opening container having a hermetic seal between the closure and thebody portion of the container wherein the means for releasing the closure from the container body will also break the seal so that the closure may be readily removed from the container body. V Y A further object of the invention is'to provide a container of the'above character wherein the closure is released from the container body by the removal of a rip strip, and wherein said rip strip is a part of the securing means and the sealing means so that the re-' moval of the rip strip breaks the seal as well as releases the securing means. 7

These and other objects will in partbe obvious and will in part be hereinafter more fully disclosed.

In the drawing which shows by way of illustration one embodiment of the invention:

Figure 1 is a sectional view through a container with the closure slipped over the end of the container before it is seated thereon.

Fig. 2 is a view showing the end seated and V to. The securing means is of a character so that the closure is permanently attached to the body until a portion of the closure or body is ruptured in order to release the closure from the body portion. In the carrying out of the invention as illustrated the closure 1s provlded with a depending flange which engages over the open end of the contain'er and closes said open end. In the lower portion of this flange is a securing means which is caused to engage a shoulder on a container body for permanently scuiing the closure to the container body-until.

the closure is ruptured for releasing the same. The flange s scored along a llne between the securlng means vand the top of the closure,

thusforming-a rip strip which may be torn placed on the container body there is a-re I shaping of the wall of the depending flange of the closure and the wall of the container bodyfwhich not only brings abouta'securing ofthe closure to the containerbodybut acompressing and embedding of the metal in the sealing means so as to hermetically seal the closure end to the container. v When theirip strip is torn awayit not only releases thesecuring means but also releasesthe seal or renders it so that it can beeasily broken andthe closure removed. I a

' Referringlmore indetail to the drawing, the body portion 1 is preferably cylindrical. Said body portion isrolled at thetopedgeto provide a hollow bead 2. This end'of the containerbody is closed by a closure 3. The

closure is attachedto the bodyby the manu facturer ofthe. container. Afterwards thecontainer is filled and the other end thereof which becomes the bottom end of the closed i package is secured by the usual double seamj. This is a common method of manufacturing containers with specially constructed easyx opening means. The closure 3. is provided witha depending flange land a centralde pression 5, thus forming a channel 6 which receives the. hollow bead 2. The container f body as initiallyformedhas an'annular recess in the outer face of the body wall adjacent the {hollow bead 6. The wall is depressed inwardly at 7 forminginclinedf portions 8,8 and this is What producestherecess. This recess maybe otherwise shaped. 1 Attached to the body in the recessforme in the outer wall is an elastic gasket 9.! This gasket 9 is preferably a 'flat ring'shape and I In Fig. ljof the f ing applied to the container and it is apparent that theflange 4 will readily pass down over the gasket and not disturb the position of'the same during the seating ofxthe' closure on the container'body. As noted above, this is accomplished by the manufacturer of the closure having a depending flange for encontainer. v The other endof the container is open and access may be readily had to the interior-of the container body. When the closure has been seated on the container body the i wall of the containerbody and the Wall of the depending flange, are subjected to'roll'ing pressure which deforms these parts causing the sealing band to be also deformedand firmly gripped so as to produce a very tight hermetic seal. As shown in the drawing, the deforming of the body portionproduces an inwardly projecting bead l0. The flange isalso provided 7 With an inwardly projecting bead 11. vThe j Wall'o' f' the container body adjacent the upper 'portionof the recess and the upper portion of the sealingband is fiattened some-what so that the sealing band 9 is deformed, a portion of the same being gripped between the 'engag- 1 ingbeads 1O and 11, and a portion of the same being grippedbetween the Wall of the container body and the depending wall of the flange above-said beads.

of the rip stripsothat When the rip strip is it removed for releasing the securing means it also breaks the seal and thus permits the cover or closure to be readily removed and replaced.

Having fully described my invention, What I claim as new and desire to secure by Letters:

Patent, is V v A containercomprising a body portion, a

the sealing gasket" for sealing thecontainer,

whereby When said rip strip is removed to' release the closure, a portion of the seallng gasket is released and exposed so that sard portion can be grasped forremoving the gasket, thereby breaking the-seal of the container. I I g r I Intestimony whereof, I affix my signature.

The depending flange 4 of the closure is M provided with a score line 12 forming at the lower edge of the depending flange a rip strip 13 With an integral projecting tongue 18a.

There is a score line 14 extending across the flange beneath the score line 12; When .a key 7 is applied to the tearing tongue 1305 the rip strip 13 may be rolled ontothe key and the metal severed along the score line 12. The rolling of the'strip onto the key Will release the securing means as the portion of the dependingfiange ofthe closurecontaining the bead 11 is torn away. It Will also uncover the sealing band to a point near the upper end of the band and this will in effectbreak the "seal. 7

It 'Will be'understood that other Ways of securing the closure tothe'container body i may be provided, and other Ways of com'pleting a hermetic sealbetween the closure and thecontainer'body-may also be provided;

- the'essential features reside in the placing portion of the container.

All that the securing means accomplishes is the mechanicalconnection of the closureto
